Common Semi Truck Electrical System Problems that Should Be Addressed ASAP

by Kaos Truck & Trailer Repair • 13 May 2025
When you're operating a semi truck, your electrical system is critical for keeping things running smoothly—from starting the engine to ensuring proper lighting and safety features. If electrical problems are ignored, they can lead to breakdowns and safety risks. At Kaos Truck & Trailer Repair, we provide mobile semi truck electrical repair in the greater Las Vegas, NV area. Here are four common semi truck electrical system issues that need quick attention. Dead or Weak Battery One of the most frequent electrical issues in semi trucks is a dead or weak battery. A battery that's not holding a charge can prevent your truck from starting, especially in cold weather.. Regular battery inspections and load testing are important to catch early signs of battery failure before it disrupts your route. Faulty Alternator The alternator is responsible for keeping the battery charged while the engine runs and for powering the truck’s electrical components. A failing alternator can cause dimming headlights, warning lights on the dashboard, or even complete power loss. If your alternator isn’t working properly, the battery won’t recharge, which will eventually leave you stranded. It's wise to have alternator output tested regularly and replaced when it shows signs of weakening. Blown Fuses and Bad Relays Fuses and relays help protect and control the flow of electricity in your truck’s circuits. If a fuse keeps blowing or a relay fails, it can disable important systems like headlights, trailer lights, or climate control. While a single blown fuse may be a relatively minor issue, repeated problems could indicate a deeper electrical fault that needs professional diagnosis and repair to prevent further damage. Corroded or Loose Wiring Connections Over time, electrical connections can become corroded or come loose, especially in older trucks or those frequently exposed to harsh weather conditions. Corrosion can lead to intermittent failures in lights, sensors, and other electronic components. If you notice issues with such components, wiring should be inspected and cleaned or tightened as needed.

4 Common Cooling System Problems in Semi Trucks

by Kaos Truck & Trailer Repair • 15 April 2025
A semi truck’s cooling system plays a vital role in preventing the engine from overheating. Given the heavy loads and long hours these trucks endure, the cooling system is put under significant stress. If it malfunctions, the engine could overheat, leading to costly repairs and potential breakdowns. Recognizing the signs of cooling system trouble early can help prevent major issues on the road. At Kaos Truck & Trailer Repair, we provide expert roadside semi truck cooling system repair in Southern Nevada. Here are four common cooling system problems that semi truck drivers should watch out for. Coolant Leaks Coolant leaks are among the most frequent cooling system problems in semi trucks. These leaks can occur in locations such as hoses, the radiator, and the water pump. When coolant levels drop too low, the engine can quickly overheat, leading to severe damage. Drivers should regularly inspect their truck for puddles of coolant under the vehicle. Promptly repairing leaks can prevent costly engine damage. Faulty Water Pump The water pump is responsible for circulating coolant through the engine and radiator. If it fails, the coolant won’t move efficiently, causing the engine to overheat. Common signs of a failing water pump include coolant leaks around the pump, unusual whining noises, or fluctuating engine temperatures. Since a malfunctioning water pump can lead to engine failure, it’s essential to replace it as soon as issues arise. Clogged or Damaged Radiator The radiator is critical for dissipating heat from the engine, but it can become clogged with debris over time. A clogged radiator restricts coolant flow, leading to overheating. External damage can also reduce the radiator’s efficiency. Drivers should inspect the radiator for visible signs of damage and ensure it remains clean and free of obstructions. Regular flushing of the cooling system helps prevent buildup inside the radiator, keeping it functioning properly. Malfunctioning Thermostat The thermostat regulates coolant flow. If it gets stuck in the closed position, coolant won’t circulate properly, causing the engine to overheat. Conversely, if it’s stuck open, the engine may run too cold. Erratic temperature gauge readings are a sign of a thermostat problem. Replacing a faulty thermostat can prevent more significant cooling system problems. 24/7 Roadside Semi Truck Repair in Southern Nevada When you need roadside truck repair in Las Vegas, NV and the surrounding area, contact Kaos Truck & Trailer Repair at  (844) 219-0633  .
